Application led September 15, .1922. Serial No. 588,36.

To all whom z't may concern:

Be it known that I, IVAN ANDR, a subject of the King of Great Britain,residing at Deland, -in the county of Volusia and State of Florida, haveinventedl certain new and l useful Improvements in Pneumatic Tires, of

which the following is a specification, refer# Ience being had thereinto the accompanying drawing. y

My invention relates to tires and in particular to pneumatic tires.

It isr the object of my invention to provide atire that is substantiallypuncturel proof, cannot blow out as an entirety, and can be repairedwhen injured in one of its units at a very .economical cost.

It is a' further object of my invention tov provide means of 'continuingto operate the tire after a `portion of it has been punctured or blownout without injury to the remainl der of the tire or to thev vehiclewhich carries it.

It is an additional object of my invention to provide the advantages ofan inner tube when desired without'the' disadvantage of it becomingpunctured or otherwise damaged by the entrance of nails and the ,like tothe casing.

It is the object of my invention to prevent the sudden collapse of thetire'and the liability ofthe tire becoming torn off when rounding aturn. It also eliminates the necessity for stopping in transit to-repair a. uncture.

t is a further -object to provide an arrangement of parts which willenable the.

operator to locate the punctured portion immediately without a long and`tedious search. IIt is further possible by my invention to carry extrasections whichf will require little 'space and can be inserted by onewith little skill in handling automobile tires.

My invention eliminates spare wheels or spare tires, repair kits, andextends the life of the lcasing due to the fact that it will prevent itfrom ever running in a collapsed position.

Referring to the drawings: y.

Fig. l is a side elevation of a portion of the tire showing in dottedlines the location of the sections.

Fi 2 is a side elevation of a portion of the tlre partially in sectionshowing the arrangement of sections with the base 2.

Fig. 3 is a side elevation of a complete wheel with the parts installed,the tire being partially in section.

Fig. 4 is a section on the line 4-4 of Fig. 2.

Fig. 5- isa plan view of one of the sections. Fig. 6 is an end view ofone of the sections.

Referringto the drawings in detail: 1 is the casing of a tire having theside beads' 2. The outer portion of the tire is filled with aseries ofinterlocking, inflated,

elastic, units designated 3. These units are provided with a recessedportion 4 on one i eng and a projecting portion'5 onthe other en f Theprojecting portion on one unit pro.

jects in to the recess portion in the other'unit. Each one of theseunits has an air chamber 6 therein. `Theother walls of the unit arecomposed of a bottom 7 and a top 8,'the top 8 being a little more thansemi-circular, occupying about of acomplete circle, while 7, the bottom,is slightlyarched.

'These sections can ,be inserted in the tire one by one interlockingwith one another and if punctured or otherwise injured can beremovedindependently. .Beneath these sections is an inner tubedesignated 9. It is substantially triangular in section having aslightly curved upper wall l0 and side walls 11 and l2. An airpassageway 13 is provided between the walls with which communicates theusual valve 14 for inflating and defiating the inner tube.

It is also to be noted that one of the sections or units 3 is providedlwith a concave inner wall 1 5 and the tube 9 will bulge, as

at 16, to provide a pneumatic projection on Acel or any other of theserles'.l

Havingdescribed my invention as herein set forth I do not desire toconfine myself` to the details, but comprehend within it suitablemodifications4 which may be found advisable nadapting my invention tovarying conditions, which modifications fall within the terms andscopeof the appended claims.

Having thus fully described my invention` what El claim as new anddesire to secure by within the casing for supporting the casing,

a pneumatic tube within said casing tosupport said sections in positionwithin said cas? ing and occupying a portion ci tbe casing adjacent tberim .zone-tbereo5 one or" said sections liaving a recessed portion, anda pneumatic projection on said tube extending in said recess whereby apneumatic interlock is formed between tbe 'inflated members adapted toprevent creeping ci said inflated members relatively to each othero l2.. ln combination, a casing `a` plurality or" removable independentnresilient pneumatic sections within said casing, -a removable pneumatictube within said casing to sup port said sections in position withinsaid casing and occupying aV portion oi the casing adjacent the rim zonethereof7 4one oi said `sections leaving a concave portion9 and a insiemebulge on said tube formed integral tlierewith adapted to fit into saidconcave porf sections interlocking with each other arranged witbinsaidcasing and removable in respect to said casing, a removable pneumatictube within said casing to support.

said sections in position within said casing, and occupying a portion ofthe casing adjacent the lrim Lzone thereof and: removable in respect ,tosaid casing, one of said' sections leaving a recess, and a projection onsaid tube fitting into the recess portion of the section forming aresilient pneumatic interlock between the' inflated members and adaptedto prevent creeping relatively to each other.,
